Actually, it's not "due to the system" that the question is not marked as answered. It's because the author, in this case Jade, has not marked it as such when she was happy with the ID. Also, as I told you many times, I do not have time to do this job for those cases where authors don't mark their questions as answered, but I will do it as soon as I will be free.

However your saying you've no time for cases where authors don't mark their questions as answered seems to make no sense, as back in 2012 ( http://www.nhm.ac.uk/natureplus/message/26220 ) Jonathan said "There are only two people who can mark posts as answered (or helpful). The person who originally started the thread and a moderator of the forum (e.g. an ID team member)." ie you were specifically given the ability to do just that. Further, from your always saying "I havent the time..." etc it looks as if you're the only one doing the marking. If so why are none of the other 5 team members on the 'on the seashore forum' doing the marking? I'm sure many of the authors don't mark their questions as answered in part by reckoning 1 of these experts will.
